[BUG] Empty docker images built in some cases by the CI server

[fbielejec]

Description

In some cases CI server builds and releases empty docker images. These are the auto-deployed to the environments and crash immediately after a reboot. Never images are never picked up since the container under the update watch process is not running at this point.

Expected behavior

If any process exist during the release the whole build should be stopped and failed.

Reproduction

See this build log : https://circleci.com/gh/district0x/memefactory/279

Solution

• [ ] Build artifacts in a separate step
• [ ] Copy them inside the docker images
